Keep service-edge routing infrastructure covered with Cisco SNTC 24x7x4 support for the ASR 9000 800G platform. This service is built for teams that cannot afford long recovery windows when a core edge component fails. Around-the-clock access to support, paired with a four-hour response target, helps shorten the gap between incident detection and corrective action. For carrier, enterprise, and large distributed environments, the value is in operational certainty. High-capacity edge platforms carry traffic that is difficult to reroute quickly, so service coverage must be aligned to the business cost of interruption. This plan is intended to support that requirement with a clear service model and a response profile suited to critical network infrastructure. Procurement teams get a defined support commitment, while operations teams get a faster path to resolution. That combination makes the service a practical choice for organizations extending the life of ASR 9000 deployments without accepting the risk of unprotected edge capacity.
